provided withv an integral. lug or handle extension 21, to permit actuation of said The spray passage 17, communicates with the mixing or carbureting chamber 22, of the carbureter 18.

iThreaded into an opening in the bottom of the carbureter 18, is the upper end of a vertical air supply tube or pipe 23, the lower open end of which projects through the opening 9, in the partition plate 7. 1 Air is supplied to the lower endof'the air tube 23, through an air. intake opening 24, formed iri. the7 funnel flue 5, below the partition ate a I j a Adjustably engaged on the air supply tube'23, is a support or bracket embracing a cylindrical collar 25, provided with a plurality of integral radial arms 26, the upper flat surfaces of which are flush with the upper end of thecollar25. The bracket 25-26, is

fadaptedqto be removably secured in an adjustedpositionuponthe tube 23, by means of a set screw 27, which threads through the collar 25,, and engages the tube 23.

;- Seated upon the support 2526, andvertically adjustable therewith is a circular metal baffle plate or disk28, 'havingopenings' 29 and .30, therein through which the pipe 12,

- and the tube 23, respectively project. Formed integrally upon the upper surface of the baffle plate 28, a short distance to the inside ofthe periphery thereof, is a circular bead or. ridge 31. v r

A, threaded opening isprovided in the top wall of the carbureter directly above the nozzle l6,and-threaded into said opening-is the ljqw e end Of .a' vertical gas pipe 32..

Secured upon the upper end of the gas pipe 32, is a burner holder comprising a chambered three way union or housing 33, having integrally formed thereon three downwardly directed curved arms or elbows 34, which communicate with the interior of the stand pipe 32, through the chamber within the union 33. Secured in the outer end of each of the elbows 34, is the upper end of a vertical burner tube 35, across the lower end of which a burner screen 36, is held by means of a burner member or ring 37. The three burners are directed downwardly and are spaced equidistantly from one another. Said burners are disposed above the ballle plate 28, to direct hot oil-gas flames thercagainst to cause heating of said baflle plate to a high temperature to heat the air surrounding the bafiie plate, and also the oil supply pipe 12, and the carbureter 18, to volatilize the oil therein to facilitate the generation of an oil-gas fuel.

As clearly shown in Figs. 1 and 3, the oilgas generating devices of the stove are inclosed by a cylindrical outer casing 38, open at both ends, and having the lower end thereof resting on the seat 10, at the inside of the retaining rim 11. The stove casing 38, is provided with a circumferential row of spaced draft openings 39, a short distance from each end of the casing. Engaged in diametrically opposite apertures provided near the upper portion of the stove casing 38, are the hooked ends of a handle 40, whereby the hydro-carbon stove may be conveniently carried. 'The supply pipe 12, is rigidly secured to the fuel can 1. Threaded or otherwise secured in the top of the union 33, is a threaded upwardly projecting connector or nipple 41, adapted to removably receive a nut cap 42, threaded thereon to securely hold a stove top or cover 43, looked upon the upper end of the casing 38, to close the same. The stove cover 43, is provided with a downwardly curved circumferential apron or flange 44. A plurality of apertures or openings 45, are provided in the top of the cover 43, to permit escape of the hot air from the interior of the stove casing 38. The nut cap 42, serves to hold the stove parts locked together to permit movement of the stove as a whole. Rigidly formed on the top of the cover 43, are a plurality of projections orknobs 47, affording rests upon whicha cooking utensil may be placed if desired.

., The operation is as follows:

With the portable hydro-carbon heating stove assembled as shown in Fig. 3, kerosene, gasolene or any other suitable hydro-carbon oil may be admitted into the fuel can 1, by removing the plug 2, and the air valve 3, associated therewith. After again inserting the plug 2, in position, and with the fuel Val e 13,c1 sed, air is pumped' into the fuel air valve 3, which of course is arranged to can 1, by means of any suitable kind of. air pump the endof which may be engaged in an opening for the purposeprovided in the be adjusted to permit air from the pump to be forced into the fuel can to exert pressure upon the oil therein.

To start the operation of the stove the 1 fuel valve 13, is opened by turning the valve stem 14, thus permitting oil from the can 1, to be forced under pressure, upwardly through the supply pipe 12, and into the carbureting chamber 22, through the passage 17, in the spray nozzle 16. As clearlyshown in Fig. 3, the lowerair intake end of the air tube 23, is disposed at a considerable distance below the carbureter 18. so that a sufficient draft is afforded through the tube 23, and in the carbureting chamber 22, to cause the air passing through the carbureter to be carburetedwith the oil sprayed from the nozzle passage 17, to form an oil-gas which rises in the pipe 32, and then passes through the elbows 34 and out through the burners. The escaping oil-gas from? the downwardly directed burners is ignited by applying a flame through an enlarged opening 46, in the flue 5, and produces a very hot blue flame which strikes against the vertically adjustable baffle plate 28, to heat the same to a high temperature and thus heat the air circulating through the stove due to the arrangement of the air openings 6, 39 and 15. The flames from the burners strikingthe baflle plate are directed upwardly to cause heating of all of the air passing upwardly around the baflle plate. f

The heat from the flames also causes heating of the oil supply pipe 12, and the carbureter 18, thereby causing rapid volatilization of the oil to facilitate carburetion of the air passing through the carbureter to generate the necessary oil'gas fuel for consumption in the stove burners. Heating of the carbureting parts acts to prevent carhoniza tion thereof. In case the carbureter becomes clogged or dirty the same may be cleaned fthrough the opening 19, by. opening the shutter 20. Access to the oil-gasgenerator mechanisms is readily had by simply removing the nut cap 42, thereby permitting removal of the stove cover 43, and the stove casing 38. Adjustment of the baffle plate 28,

is permitted by releasing the set screw 27, which holds the baffle plate bracket in posia tion on the air tube 23.

The heated air from the stove escapes from the openings 45, in the stove cover 13, toheat the room wherein the stove is placed. Heat is also radiated by the casing 38, and the cover 43. The process of oil-gas generation is stopped by simply closing the oil supply valve 13, and permitting the generated oil-gas to burn out.

If desired the stove may be used as a fuel tank, oil-gas generating means mounted thereon to receive oil therefrom, said generating means including adjustable heating means, said generating means being provided with a removable plate. a 2. A. hydro-carbon burner embracing a pressure fuel a tank, a carbureter mounted thereon to receive oil therefrom, a removable plate on the end of the carbureter, means for supplying air to the carbureter to be mixed with the oil to form an oil-gas, and burner members connected with said carbureter adapted to burn the generated oilgas as a fuel for heating purposes.
